LASTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 631,609, dated August 22, 1899. Application filed May 6, 1899. $erial No. 715 ,825. (No model.)

To all whom it may concern.-

Be it known that I, KARL -W. BERGLUND, a citizen of the United States, residing at Brockton,in the county of Plymouth and State of Massachusetts, have invented new and usef ul Improvements in Devices for Lasting Toe Portions of Welted Boots and Shoes, of which the following is a specification.

This invention relates to an improved device for lasting the toe portion of welted boots and shoes; and it consists of an arched resilient wire having pointed ends bent at substantially right angles to the arched portion of the wire and adapted to be removably driven into the vamp and inner sole for the purpose of holding the toe portion of the vamp in its proper position relative to the inner sole preparatory to and during the operation of sewing together the vamp, inner sole, and welt, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein- Figure 1 represents a bottom view of a boot or shoe, showing the bent wire or staple se-' cured to the toe portion during the lasting and sewing operation. Fig. 2 represents a longitudinal section on the line 2 2 shown in Fig. 1. Fig. 3 represents a detail perspective view of my improved metal wire toe-lasting wire staple.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, A represents the last.

B represents the inner sole, and O represents the vamp, of a boot or shoe, as usual.

0 represents the turned-over lip of the vamp at the toe portion of the boot or shoe, which is usually turned over by the wiper of a lasting-machine, as is common in the art of last ing boots and shoes.

B is the lip formed on the under side of the inner sole, and B" is the channel therein, as usual.

Heretofore the vamp toe portion of a boot or shoe has ordinarily been lasted first by means of tacks driven through the turnedover portion of the vamp and into the inner sole and afterward by stringing through the vamp and lip on the inner sole, after which the tacks are removed to allow the stitching to be done through the welt, inner sole, and vamp or upper. Such operation of lasting the toe portion of a boot or shoe is laborious and expensive, as it requires, first, lasting by means of driven tacks; second, stringing through the vamp and lip of the inner sole, and, third, removing the tacks preparatory to sewing the parts together and sometimes the removing of the string by means of which the vamp is temporarily attached to the inner sole. With my device I dispense with both tacking and stringing, and I use for the purpose of lasting the toe portion of a boot or shoe, so as to secure the turned-over vamp portion to the inner sole and to hold it in such a'position during the operation of sewing the welt, upper, and inner sole together, a device as follows:

I use a metal Wire or staple D, provided at its ends with prongs d d, as shown in Fig. 3, which are driven through the turned-over toe portion of the upper and into the inner sole, as shown in Figs. 1 and 2. The said wire is made of spring-steel or spring metal and capable of being bent to an arch corresponding to the shape of the toe portion of the boot or shoe that is to be lasted. The said arched or curved Wire staple is made to fit outside of the upturned vamp toe portion, as shown in Figs. 1 and 2, when the ends of said wire staple are secured to the vamp and inner sole, thus causing the said vamp portion to be firmly held against the inner sole during the subsequent sewing together of the vamp, inner sole, and welt, by means of a Goodyear or other single-thread sewing-machine. The said wire staple remains secured to the vamp and inner sole during the welt-sewing operation, and it offers no obstruction to such sewing together of the parts. After the said parts have thus been united I remove the wire staple by means of any suitable tool without injury to said Wire staple, which may be used indefinitely from time to time.

What I wish to secure by Letters Patent andclaim is The herein-described device for lasting the vamp toe portions of boots and shoes, comprising an arched resilient wire having pointed ends bent at substantially right angles to the arched portion of the wire and adapted to be removably driven into the vamp and my hand in presence of two subscribing witinner sole, the curved or arched portion of nesses. the Wire operating to hold the upturned vamp 1 toe portion in position on the innersole during KARL BERGLUND' 5 the sewing operation after which it is removed, \Vitnesses:

substantially as described. ALBAN ANDREN,

In testimony whereof I have hereunto set KARL A. ANDREN.
